Seamless Pipe is usually made from a solid round metal billet which is heated and pushed or pulled over a form until the material is shaped into a hollow tube. The Seamless Pipe is then finished to dimensional and wall thickness specifications through the process of hot-rolling, cold-rolling or cold-drawing. Seamless Pipe is mostly used to carry high pressure gas or fluid within the Oil, Gas, Filtration, Refrigeration, Refining, Petrochemical and Offshore Industries.
